I test a web server run on a 24-core server. When server get a message, it would read/write mnesia and return a message to client. All of the mnesia tables are ram_copies and disc_copies.<br>I do a stress test and found that the heighest value of cpu load is only 900%, I get I/O load by iostat and it is idle, so I guess the system bottleneck is mnesia, but I found the reductions counter of mnesia's process are low.<br>
Is my guess right?<br>
